About

2011-2018 Built the product function at PagerDuty (YC S10) -- which involved everything from hiring the PMs to sales enablement, competitive intel, partnerships and pricing. Moved PD to multi-product & established an enterprise motion.

2018-2021 Built the product org at Sentry.io following a lot of the same playbook. Grew from one SKU (errors) to multiple product at multiple price points.

2022: we're working on bringing high quality demos to all SaaS orgs -- want to sell more, talk to me!
